A memorial service is planned for Thursday for a McHenry County man who died after his motorcycle collided with a car whose driver was under the influence of alcohol, authorities said.

Steven Thomas, 26, of Richmond, died Aug. 11 after his organs were harvested for donation, said his mother, Becky Thomas.

The man who authorities said collided with Thomas' motorcycle on Aug. 10 — Christian Heaney, 44, of Johnsburg — was initially charged with aggravated DUI causing injury and released from custody after posting bond. But after Thomas died, authorities increased the charge to aggravated DUI causing death, and Heaney appeared in court on the new charge on Tuesday.

Heaney was driving a silver 2014 Range Rover southbound on U.S. Highway 12 in Richmond, near the Wisconsin state line, when he collided with Thomas and his motorcycle, according to court documents. Thomas was pronounced dead at Advocate Condell Medical Center in Libertyville.

With the enhanced charge against Heaney, his bond was increased tenfold, to $250,000. In McHenry County court Tuesday, Heaney's lawyer, Mark Facchini, sought to have his client's bond lowered to $100,000, saying Heaney was not a threat to the public. That was denied, but hours after the hearing, Heaney posted the required $25,000 and was released.

Thomas grew up in Richmond, working on farms in the rural community both before and since he graduated from Richmond-Burton High School in 2008, his mother said. He was employed by Geils Farms in Harvard for the last four years, she said.

"He was a very hard worker, but he loved what he was doing," Becky Thomas said.

Thomas participated in football and weightlifting at Richmond-Burton and was a fan of county fairs, tractor pulls and bowling.

His mother said Thomas enjoyed lending a hand — "He'd help anybody and everybody," she said — and noted that, even in death, he was still helping others through the donation of his organs.

Besides his mom, Thomas is survived by his father Ted and sister Samantha.

Visitation for Steven Thomas is planned for 1 to 4 p.m. Thursday at Ehorn-Adams Funeral Home, 10011 Main St. in Richmond, with a memorial service starting at 4 p.m. at the funeral home.
